Hmm... I haven't tried screwing with it too much... I tried doing a
'fink' or one of the other distro tools - it fetched the Dosbox source
just fine, but the compile stopped when it failed to locate X11.h or
something similar. I have it on the system, so it's probably a
Makefile assumption as to INCLUDEPATH or something similar. I just
haven't had time to dig into it. It's really just to play DOS games
("Master of Orion I", "X-COM", "Colonization", etc.) so I'll probably
dig into it in the depths of Winter at Pole, when I'm bored and need a
nostalgia fix. It's entirely uncritical for "real" work.

As I thought... but I don't think they have released a Mac OS X
version of "Starcraft" and "Starcraft: Broodwars" - more unessential
retro-gaming. I do have genuine copies of both for Windows, so it's
probably easiest to just finish setting up Parallels and run the DOS
versions. I was just hoping to stay native where native was possible,
but not, apparently, in this case.
I just received my shipment of items from this auction:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220149564798
which should have been a load of recyclable TK50 media. Instead of
CompacTape, however, they are all CompacTape III. I think these were
TK85 2.6gb media. Does anyone know if they will still be writable
with the standard format in a TK50? Or do I have a bunch of useless
DLT I tapes?

I've seen that when the quartz window isn't really clean and the
UV hasn't quite done the full job. I have found some vendors
eproms need a little more time to cook.
Ove 26 years I think I've only seen one that really had a stuck
bit and that was a blown output pin.

A friend might have a Dysan Pat-2+ 5.25" floppy drive tester held for
me, but we both have no experience with it. Assuming it comes with the
alignment disk and manual, and functions, is it a worthwhile piece of
equipment to have? I am not a die-hard techie -- I do not own an
oscilloscope -- so I might grab it to keep my drives aligned, but not if
it's more placebo than functional.
If anyone has had experience using this unit or one like it, I'd like to
hear your thoughts.

I have a reasonable Decmate I / PDP8 with dual RX02's in a tower and
spare parts CRT/Keyboard, spare motherboard. It boots up nicely,
includes serial port board and back cover. I've enjoyed it for the past
year, but now have to get it out of my workspace. Open to a reasonable
offer, especially if the buyer can pick it up in Southern NH.

While checking out a old hangout I found a copy of IBM's Hollywood software
Version 1.0 (on 3.5 FD), complete in the box for $1.81 plus tax. There was
not much else there like it was in the long ago past. Speaking of Hollywood,
the Hollywood video store near us is closing and I went dumpster driving the
other night and found that they had tossed all the video game cases that had
been on display. Most but not all were empty, I found PS2 and PS3 DVD's in
some of the cases. It got too dark and I had to stop pulling cases from the
dumpster but there was over 150 cases left in the trash.

Hi all --
Just picked up an SGI Crimson this afternoon, which should prove to be a
fun machine to play around with once I get it running... a few questions
for those who've dealt with these before...
- What kind of power cable does this thing take? I've not yet seen
anything like the connector on the back of this thing... can I plug
this thing into a regular household outlet (that can supply the massive
power requirements) or am I going to have to rewire my house? :)
- What version of IRIX do you recommend running? I have a copy of 5.3,
and 6.5, but I know that 6.5's too new for this beast.
Anyone out there have a keyboard/mouse they're willing to part with (or
know where I can find one?). This thing's got a 15-pin D-Sub connector
on it and I of course don't have anything compatible...
Thanks, as always...
- Josh
Man, I seem to be asking for a lot of keyboards lately :). Got a
working Acorn A5000 sans keyboard and mouse. Connector looks like PS/2,
but of course it's not.
Anyone have a spare set?
Thanks again,
Josh

The 9000 was obsoleted by the NVAX chip before the 9000 hit the street.
"the mainframe world" acceptance of a CPU is the stupidest-ass thing
a company could ever ever want. On a.f.c there were some references
to emulating Unisys architectures on Intel hardware, and I followed the
links to the trade press rags, and the rags were filled with a bunch of
useless self-important balloon-filling about CPU technologies with no evidence
that anywhere anyone understood what the emulation layer actually
did. I came away not knowing what the emulation layer actually did either
(classic CPU-technology-on-the-mind poisoning of those who should know
better).
There are about ten thousand markets that DEC served quite well, and
it's a shame they put all that effort and money into neglecting those
markets and trying to do a mainframe.

Stack it up with all those other CPU's without peripherals, huh? :-).

Mainframes are really good at some things, sometimes they are decent
number crunchers in terms of pure FLOPS but it has been three to four
decades since they delivered any punch in terms of FLOPS per dollar.
